【摘要】：为保护珍贵的周原甲骨文物,了解文物保存现状,将1977年出土周原甲骨与2010年出土周原甲骨及新鲜甲骨进行对比研究。采用扫描电镜、X荧光光谱、X衍射、红外光谱等方法,从表面微观特征、元素成分、化学结构等方面对周原甲骨进行分析。结果表明,经历了两千多年地下埋藏、出土后的酸洗及三十多年保存,1977年出土的周原甲骨,表面疏松粉化,微孔结构逐渐消失,出现走向无序的裂纹及片层状脱落,无机成分以羟基磷灰石为主,蛋白质等有机成分已全部分解。2010年出土的周原甲骨出土后未经任何保护处理,目前表面未出现明显粉化与脱落,仍有少量有机物存在。本研究成果可以作为甲骨文物保护方法与保护材料研究的基础参考资料。
[Abstract]:In order to protect the precious oracle bone of Zhou Yuan and understand the present situation of cultural relic preservation, a comparative study was carried out between the bones unearthed in 1977 and those unearthed in 2010 and those unearthed in 2010. By means of scanning electron microscope (SEM) and X-ray diffraction (XRD) and infrared spectroscopy (IR), Zhou Yuan's oracle bone was analyzed in terms of surface microcosmic characteristics, elemental composition and chemical structure. The results show that after more than two thousand years of underground burial, acid pickling and more than 30 years preservation after unearthed, Zhou Yuan's oracle bone unearthed in 1977 was loosely powdered, and the micropore structure gradually disappeared, resulting in disordered cracks and lamellar shedding. The inorganic components were mainly hydroxyapatite, and the organic components such as protein had been decomposed completely. After unearthed Zhou Yuan's oracle bone in 2010, without any protection treatment, there was no obvious pulverization and shedding on the surface at present, and a small amount of organic matter still existed. The results of this study can be used as the basic reference for the research on the methods and materials of oracle bone preservation.
